摘要: 根据对含水钠长石玻璃的FTIR光谱研究,认为水在钠长石熔体中同时以OH-和H2O形式存在,这分别对应于FTIR光谱中的4 500 cm-1及5 200 cm-1谱峰。此外,研究表明在溶解初期水主要以OH-存在于熔体中,随着熔体中水含量的升高,H2O分子则成为主要的溶解类型。而且,水的溶解类型变化与熔体粘度变化特征是一致的。Abstract: On the basis of FTIR spectroscopy study on hydrous albite glasses, it is concluded that water dissolves into melts as OH- and H2O simultaneously and these are accordance with 4 500 cm-1 and 5 200 cm-1 in FTIR spectra respectively. In addition, studies also indicate that OH- is dominant in the early solubility and H2O becomes important with higher water contents. And the change of water solubility speciation in melts is agreement with the character of hydrous melt.
